Visiting Mount Fuji from Lake Kawaguchiko is a must for anyone traveling to Japan and since it’s pretty close to Tokyo, a day trip is the best way to see it.
If you are searching for the best view of Mount Fuji there are a couple of places to chose from and even though you might be tempted to go and see it from Hakone because of the convenient way to get there and the multitude of day passes available, I recommend the less traveled path, Lake Kawaguchiko.
